IMPRovEMENr iN RAiLwAv-cAR-AXLE LuBRlcAi-ons.

`The Schedule referred to in these Letters Patent and making parl.' of the lame.

I, l(JHARLES HYATT, of the city of Buffalo, in the county of Erie and State of New York, have invented an improved Automatic Lubrieator for J ouruals, of which the-:following is a specification.

My invention relates to improvement-s in the construction and operation of that class of lubricatois for railroad-car axles which consistsof' rollers, covered with some absorbent material, for` conveying the oilto the axle, and which, being held against the axle by springs or similar device, operate, through friction, with and by the rotation of the axle. Heretotorm'these lubricating-rollers have generally been confined in close oil-boxes, either 'forming part of the' axle box itself, or permaneut-ly-seeuied within it, the lubricating-rollers, or'the absorbing .material with which they are covered, being kept in close contact wit-l1 the axle, without any provision for cleaning it or removing froml it the il'npalpa'ble metallic scale consequent on friction.

Experience has shown that this product of friction,

together with the dust and other impurities which iind their way into the oil, settle on the absorbing material of the rollers, clog upthe. spaces between its fibres, and, in course ot' time, form a smooth conipact surface incapable of supplying the journal with oil in the desired quantity, thereby rendering the lubricator, in ameasure, inoperative.

l My invention is designedv to obviate these, objec-v tions to the use of such lubricators; and

The improvement consists in constructing the lubricating-roller with grooves around its outer periphery, so that the surplus oil, as expressed by with the axle will nd a ready channel of escape, and in providing the roller with a series of tufts or wipers ot' suitable material,.wherewith to clean,as well aslubricate the journals. y

In the accompanying drawing- Figure l represents a sectional end view of the box and roller. l

' Figure 2, a'longitudinal sectional vicwof the box,

showing the construction and. bearings of 'the roller.

A A' represents the lubiicatoibox,tlie two ends A'. heilig cut into a semi-circular shape so as to it loosely around the ear-,axle without impinging ou it, yet conforming sufficiently to the contour of .the be retained in position by it.

llhe sides A do not extend' sofar downward as the axle as to cndsA, so that openings are left for the free ""crcnlaf within the lugs B, and which forni the bearings of the lubricating-roller, the spiral springs serving to' keep the Aroller in therequired contact with the car-axle.

.Dis the lubricating-roller, made of wood or other suitable material, and cut with grooves, d, around 'its circumference. p

'Duitser i'vipeiis-'EY of'fcottoinvspenge, or othersuitable material, are secured at intervals in these grooves around the roller, and a band or bands, e, ot` similar material, may also be secured around the roller.

G is the car-axle to be lubricated.

' By any convenient means of access on the top or side of theaxlebox,the lubricating-box is inserted and placed in position partly around-and beneath-the axle, as shownin the drawing, the oil contained in the axle-box having free access-to the interior of the Vlubricating-box.

The lubricating-roller, with its axle-bearing in the Spring-bearings (l, will he sustained in position, and, by the action ofthe spiral springs, brought into c011- taet with the car-axle, whereby, through the revolution of the car-axle, it is made to revolve, the tufts E successively dipping in theoil andhibricatiug and cleaning the axle, the surplus oil flowing back into the boxfalong the grooves ll, and, in its passage, satu-4 rating more completely the succeeding tufts at the moment of their contact with the car-axle.

As thewipers successively leave the car-axle and eomiu contact with the oil below', they will spread out and'leavewith theoil the greater portion of the impurities they have removed from'the'car-axle, which impurities will dep'osit iu the bottom of kthe axle-box.

What I claim as my invention isl rlhc roller D, constructed substantially as described, with grooves d, and provided with tufts or wipers E. as and for the purpose specied. v
